From an Amazon sale. Mitutoyo 100-125 mm .01 micrometer . Sometime, I'll find a 125-150 and call it good. I like using metric when the parts are made in metric. I measured a couple of shafts , I should have used a metric mike instead of grabbing the first one I found. I wouldn't have to look it up on the chart. they were 17mm and 16mm, much simpler when ordering sprockets.
